CentOS7+apache+php7+mysql5.7配置教程详解

				?

									yum upgrade

									yum install net-tools

安装apache

关闭SELinux

编辑器打开 etc/selinux/config 文件，找到 SELINUX=enforcing 字段，将其改成 SELINUX=disabled ，并重启设备。

				?

									yum -y install httpd mod_ssl

配置防火墙

				?

									firewall-cmd --permanent --add-port=80/tcp

									firewall-cmd --permanent --add-port=443/tcp

									firewall-cmd --reload

开机启动

				?

									systemctl start httpd

									systemctl enable httpd

终端输入如下指令检查httpd的运行状态

				?

									sudo systemctl status httpd

安装PHP7

添加源

				?

									rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

									rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

安装

				?

									yum install php70w

安装mysql5.7

1.安装wget

				?

									yum -y install wget

2.安装源

				?

									wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm

									 rpm -ivh mysql57-community-release-el7-8.noarch.rpm

3.安装mysql

				?

									yum install mysql-server

4.启动mysql服务

				?

									systemctl start mysqld

5.查看MySQL的启动状态

				?

									systemctl status mysqld

6.开机启动

				?

									systemctl enable mysqld

									 systemctl daemon-reload

7.修改root本地登录密码

查找mysql生成的随机密码

				?

									grep 'temporary password' /var/log/mysqld.log

									 mysql -uroot -p

修改密码，注意：mysql5.7默认安装了密码安全检查插件（validate_password），默认密码检查策略要求密码必须包含：大小写字母、数字和特殊符号，并且长度不能少于8位。否则会提示ERROR 1819 (HY000): Your password does not satisfy the current policy requirements错误

				?

									ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass4!';

8.配置默认编码为utf8

修改/etc/my.cnf配置文件，在[mysqld]下添加编码配置

				?

									[mysqld]

									 character_set_server=utf8

									 init_connect='SET NAMES utf8'

9.配置mysql远程连接

				?

									  mysql -uroot -p

									  use mysql;

									  Grant all on *.* to 'root'@'%' identified by 'root用户的密码' with grant option;

									flush privileges;

然后用以下命令查看哪些用户和host可以访问，%代表任意ip地址

				?

									select user,host from user;

防火墙添加3306端口

				?

									firewall-cmd --zone=public --add-port=3306/tcp --permanent

									firewall-cmd --reload

10.mysql忘记密码

1.修改MySQL的配置文件（默认为/etc/my.cnf）,在[mysqld]下添加一行skip-grant-tables

2.service mysqld restart后，即可直接用mysql进入

				?

									mysql> update mysql.user set authentication_string=password('123qwe') where user='root' and Host = 'localhost';

									  mysql> flush privileges;

									  mysql> quit;
